A mixture of benzene and toluene is in a tank whose pressure is maintained at 2.0 atm. Observation through a sight glass on the vessel shows that half of the tank volume is occupied by liquid. Analysis shows that the liquid contains 50.0 wt% benzene and the balance toluene. Raoult's law applies at all composition s, and the density of the liquid is essentially independent of temperature. Estimate (a) the temperature and (b) the fraction of the system mass in...

A mixture of 20.0 mol% benzene, 5.00 mol% toluene, and 75.0 mol% air is compressed isothermally at 70 degrees C until condensation first appears. What is the mole fraction of benzene in the condensate? You may assume that air is noncondensable (and thus its vapor pressure is large) and this system obeys Raoult's Law. Note: when solving Antoine's equation it is best to keep all sig figs through calculation and then truncate them at the end. Question options: 0.605, 0.832,...
